[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0078] The chassis frame provided by the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, it includes: an upper front beam 4, a lower front beam 5, an upper rear beam 6, a lower rear beam 7 and two side panel assemblies 8;

[0079] The two side panel assemblies 8 are arranged in parallel, and the rear ends thereof have a stacked and connected rear vertical beam 82;

[0080] The upper front beam 4 is connected between the upper front ends of the two side panel assemblies 8, and the lower front beam 5 is connected between the lower front ends of the two side panel assemblies 8 to form a frame front frame, which is used to install and fix multiple front board card assemblies 2 in parallel; wherein, as Figure 1 As shown, the front frame is equivalent to the front port of the chassis frame;

[0081] The upper rear beam 6 and the lower rear beam 7 are both high-strength beams, and the upper rear beam 6 is connected between the upper ends of the rear vertical beams 82 of the two side panel assemblies 8, and the lower rear beam 7 is connected between the lower ends of the rear vertical beams 82 of the two side panel assemblies 8 to form a frame rear frame. The front part of the frame rear frame is used to install and fix the back panel assembly 1, and the rear part is used to install and fix multiple rear panel card assemblies 3 in parallel. Figure 1 As shown, the frame back frame is equivalent to the rear port of the chassis frame.

[0082] It should be noted that if Figure 1 As shown, the two side panel assemblies 8 are equivalent to the left and right panel assemblies of the chassis frame, and the rear ends of both have stacked and connected rear vertical beams 82, which improves the strength of the rear ends of the two side panel assemblies 8, and the upper rear beam 6 and the lower rear beam 7 are both high-strength beams, wherein, as shown in FIG. Figure 6As shown, both the upper rear beam 6 and the lower rear beam 7 can be made of high-strength profiles, and the upper rear beam 6 is connected between the upper ends of the rear vertical beams 82 of the two side panel assemblies 8, and the lower rear beam 7 is connected between the lower ends of the rear vertical beams 82 of the two side panel assemblies 8, thereby forming a high-strength frame rear frame, which also improves the strength and rigidity of the rear part of the chassis frame. Then, after the upper back panel assembly 1 is installed at the front of the frame rear frame and multiple rear board assemblies 3 are installed in parallel at the rear, it can help ensure the relative stability of the chassis under working conditions, that is, the chassis can have a smaller response under vibration conditions, which can be beneficial to improving the vibration resistance of the chassis.

[0083] In addition, if Figure 1 As described above, the upper front beam 4, the lower front beam 5, the upper rear beam 6 and the lower rear beam 7 are all cross beams, and existing profiles can be used. As described above, in particular, the upper rear beam 6 and the lower rear beam 7 can be made of high-strength profiles, which can help save the manufacturing cost of the chassis frame; in addition, Figure 1 The chassis frame further includes: an upper plate assembly 20 and a lower plate assembly, the upper plate assembly 20 is mounted and fixed between the upper ends of the two side plate assemblies 8, the front end and the rear end of the upper plate assembly 20 are connected and fixed one by one with the upper front beam 4 and the upper rear beam 6; the lower plate assembly is mounted and fixed between the lower ends of the two side plate assemblies 8, the front end and the rear end of the lower plate assembly are connected and fixed one by one with the lower front beam 5 and the lower rear beam 7, and the upper plate assembly 20 may be provided with a plurality of ventilation holes;

[0084] The rear frame is assembled by the upper rear beam 6, the lower rear beam 7 and the rear ends of the two side panel assemblies 8. Figure 2 As shown, the back panel assembly 1 is installed at the front of the rear frame, as shown in FIG. Figure 10 As shown, multiple rear card assemblies 3 are installed in parallel at the rear of the frame rear frame, and the rear card connectors of the multiple rear card assemblies 3 are plugged into the multiple backplane connectors 11 of the backplane assembly 1 in a one-to-one correspondence; the frame front frame is assembled by enclosing the upper front beam 4, the lower front beam 5 and the front ends of the two side panel assemblies 8, as shown Figure 11As shown, multiple front card assemblies 2 are mounted in parallel on the front frame, and the front card connectors 21 of the multiple front card assemblies 2 are plugged into the multiple backplane connectors 11 of the backplane assembly 1 in a one-to-one correspondence. This ensures that the connection between the front card connectors 21 of the front card assemblies 2 and the backplane connectors 11 of the backplane assembly 1 is located at the rear of the chassis frame, and the connection between the backplane connector 11 of the backplane assembly 1 and the rear card connector of the rear card assembly 3 is also located at the rear of the chassis frame. This means that the connectors on the front card assemblies 2, backplane assembly 1, and rear card assemblies 3 of the chassis are all located at the rear of the chassis frame, thus ensuring that the connectors for input and output signal lines are located at the rear of the chassis frame. Furthermore, the backplane assembly 1 and the multiple rear card assemblies 3 are respectively mounted and fixed to the rear of the chassis frame, while the multiple front card assemblies 2 are mounted and fixed to the front of the chassis frame. This helps form a relatively stable overall chassis, thereby maintaining relative stability under operating conditions, generating minimal displacement and response, and thus ensuring the chassis's vibration resistance.

[0085] That is to say, this solution improves the structural form of the rear part of the chassis frame (the part with greater load or the key part). On the one hand, the rear ends of the two side panel assemblies 8 are provided with stacked and connected rear vertical beams 82 to strengthen the strength of the rear ends of the two side panel assemblies 8. On the other hand, the upper rear beam 6 and the lower rear beam 7 are both high-strength beams, and the upper rear beam 6 is connected between the upper rear ends of the two side panel assemblies 8, and the lower rear beam 7 is connected between the lower rear ends of the two side panel assemblies 8, thereby forming a high-strength frame rear frame, which also improves the strength and rigidity of the rear part of the chassis frame. In this way, after the back panel assembly 1 is installed at the front of the frame rear frame and multiple rear board assemblies 3 are installed in parallel at the rear, the chassis can be ensured to be relatively stable under working conditions, which also ensures that the chassis has a smaller response under vibration conditions, which can help improve the vibration resistance of the chassis.

[0086] In this program, if Figure 4 As shown, the side panel assembly 8 comprises at least: a side panel 83 and a rear vertical beam 82;

[0087] The rear end of the side panel 83 is connected to the rear vertical beam 82 in a stacked manner;

[0088] like Figure 2 As shown, the upper front beam 4 is connected between the upper front ends of the two side plates 83, and the lower front beam 5 is connected between the lower front ends of the two side plates 83;

[0089] like Figure 1 As shown, one end of the upper rear beam 6 is connected to the upper end of the rear vertical beam 82 and the upper rear end of the side plate 83 on one side, and the other end is connected to the upper end of the rear vertical beam 82 and the upper rear end of the side plate 83 on the other side;

[0090] One end of the lower rear beam 7 is connected to the lower end of the rear vertical beam 82 on one side and the lower rear end of the side plate 83 , and the other end is connected to the lower end of the rear vertical beam 82 on the other side and the lower rear end of the side plate 83 .

[0091] It should be noted that if Figure 4 As shown, after the rear end of the side panel 83 is fitted and stacked with the rear vertical beam 82, the two can be connected and fixed by a plurality of second screws 86 of the side panel; Figure 1 As shown, both ends of the upper front beam 4 can be connected and fixed one by one with the upper front end portions of the two side panels 83 by means of upper front beam screws 813, and both ends of the lower front beam 5 can be connected and fixed one by one with the lower front end portions of the two side panels 83 by means of lower front beam screws 814; each end of the upper rear beam 6 can be connected and fixed with the upper end portion of the rear vertical beam 82 on its side and the upper rear end portion of the side panel 83 by means of upper rear beam screws 815; each end of the lower rear beam 7 can be connected and fixed with the lower end portion of the rear vertical beam 82 on its side and the lower rear end portion of the side panel 83 by means of lower rear beam screws 816.

[0092] That is to say, the rear end portion of the side panel assembly 8 is a stacked connection of the rear end portion of the side panel 83 and the rear vertical beam 82, and each end of the upper rear beam 6 is connected and fixed to the upper end portion of the rear vertical beam 82 on its side and the upper rear end portion of the side panel 83, and each end of the lower rear beam 7 is connected and fixed to the lower end portion of the rear vertical beam 82 on its side and the lower rear end portion of the side panel 83. In this way, the strength and rigidity of the rear portion of the chassis frame can be improved.

[0093] In addition, the upper end of the back panel assembly 1 is mounted and fixed to the front of the upper rear beam 6, and the lower end is mounted and fixed to the front of the lower rear beam 7; the upper ends of the plurality of rear board assemblies 3 are mounted and fixed in parallel to the rear of the upper rear beam 6, and the lower ends are mounted and fixed in parallel to the rear of the lower rear beam 7; the upper ends of the plurality of front board assemblies 2 are mounted and fixed in parallel to the upper front beam 4, and the lower ends are mounted and fixed in parallel to the lower front beam 5; that is, when the back panel assembly 1 and the rear board assembly 3 are mounted on the chassis frame, their upper ends are respectively mounted and fixed to the upper rear beam 6, and the lower end is respectively mounted and fixed to the front and rear of the lower rear beam 7; wherein, the upper end and the lower end of the back panel assembly 1 are respectively mounted on the front of the upper rear beam 6 and the front of the lower rear beam 7, and can be fixed by screws; after the rear panel connector of the rear card assembly 3 is accurately inserted into the corresponding back panel connector of the back panel assembly 1, and the upper end and the lower end of the rear card assembly 3 are respectively mounted on the rear of the upper rear beam 6 and the rear of the lower rear beam 7, they can be screwed with the nut strips on the corresponding rear beams (such as Figure 1 Tighten as shown).

[0094] In addition, a plurality of guide rails 30 are provided on the lower plate assembly of the chassis frame, so that the plurality of front card assemblies 2 can be pushed into the chassis frame one by one along the plurality of guide rails 30. After the front card assembly 2 is pushed into the chassis frame along the guide rails 30, the front card connector 11 is inserted into the corresponding backplane connector 11 of the backplane assembly 1, and the upper end of the front card assembly 1 is fixed to the nut strip in the upper front beam 4 by screws (such as Figure 2 As shown), the lower end is fixed to the nut strip in the lower front beam 5 by screw locking (as shown Figure 2 shown).

[0095] That is to say, the backplane assembly 1 and the rear board assembly 3 are respectively installed and fixed between the front and rear parts of the upper and lower rear beams, which can help the chassis form a relatively stable whole, thereby helping to ensure the vibration resistance of the chassis.

[0096] Specifically, if Figure 4 As shown, the cross-sectional shape of the rear vertical beam 82 is L-shaped;

[0097] The rear end of the side panel 83 is connected to the first side portion of the rear vertical beam 82 by being stacked; wherein the rear end of the side panel 83 is connected to the first side portion of the rear vertical beam 82 by being fitted;

[0098] like Figure 1 As shown, one end of the upper rear beam 6 is connected to the upper end of the first side portion of the rear vertical beam 82 on one side and the upper rear end portion of the side plate 83, and the other end is connected to the upper end of the first side portion of the rear vertical beam 82 on the other side and the upper rear end portion of the side plate 83;

[0099] One end of the lower rear beam 7 is connected to the lower end of the first side portion of the rear vertical beam 82 on one side and the lower rear end portion of the side panel 83, and the other end is connected to the lower end of the first side portion of the rear vertical beam 82 on the other side and the lower rear end portion of the side panel 83. In other words, the rear vertical beam 82 is an L-shaped vertical beam, which can improve the structural strength and rigidity of the rear vertical beam 82, and further improve the structural strength and rigidity of the rear portion of the chassis frame.

[0100] Further, if Figure 4 and Figure 5 As shown, the first side portion of the rear vertical beam 82 is provided with a stacking groove for positioning the rear end portion of the side panel 83, which can enable the rear end portion of the side panel 83 and the first side portion of the rear vertical beam 82 to be quickly positioned and stacked, and can also make the stacking connection between the rear end portion of the side panel 83 and the first side portion of the rear vertical beam 82 more stable.

[0101] Furthermore, if Figure 8 As shown, the chassis frame provided by the embodiment of the present invention further includes a back 10;

[0102] The middle part of the back plate 10 is hollowed out, and its structure can be referred to Figure 9 As shown;

[0103] like Figure 8 As shown, the middle portion of the back plate 10 can pass through the front frame of the frame, and the rear portion thereof is assembled and connected with the front portions of the second side portions of the two rear vertical beams 82 respectively.

[0104] Among them, the middle part (hollow part) of the back panel 10 can pass through the front frame of the chassis frame to the rear frame of the frame, and the rear part (rear panel surface) of the back panel 10 is fitted and installed on the front part of the second side part of the two rear vertical beams 83, and is connected and fixed in the form of back panel screws 102+washers, that is, the rear part of the chassis frame is connected and fixed to the back panel 10 through washers and screws; that is, the front part (front beam surface) of the second side part of the two rear vertical beams 83 serves as the installation surface of the rear of the chassis frame, and is fixed by washers+screws. It is fixed to the rear of the back panel 10. As can be seen from the above, the back panel assembly 1 and multiple rear board assemblies 3 are centrally installed and fixed to the rear of the chassis. The rear of the chassis is installed and fixed to the back panel 10. Of course, the back panel 10 can be installed and fixed to a seismic cabinet, that is, the rear of the chassis can be installed and fixed in the seismic cabinet through the back panel 10. In this way, under working conditions, the response of the relevant connections of the chassis can be minimized, the stability of the relevant connections can be guaranteed, and the reliability of the chassis in the vibration environment of the seismic cabinet can be guaranteed. Of course, the upper and lower ends of the frame rear frame can also be provided with angle irons, which are used to connect and fix to the upper and lower edges of the hollowed-out portion of the back panel 10 one by one. Among them, the upper rear beam 6 and the lower rear beam 7 can be designed as L-shaped rear beams similar to the rear vertical beam 83, which makes it easier to install and fix the rear of the back panel 10 to the second side of the upper rear beam 6 or the lower rear beam 7.

[0108] One end of the lower front beam 5 is connected to the lower end of the front vertical beam 81 and the lower front end of the side plate 83 on one side, and the other end is connected to the lower end of the front vertical beam 81 and the lower front end of the side plate 83 on the other side.

[0109] It should be noted that if Figure 4 As shown, after the front end of the side panel 83 is stacked with the front vertical beam 81, the two can be connected and fixed by a plurality of first screws 85 of the side panel; Figure 1As shown, each end of the upper front beam 4 can be connected and fixed to the upper end of the front vertical beam 81 on the side and the upper front end of the side plate 83 by the upper front beam screw 813; each end of the lower front beam 5 can be connected and fixed to the lower end of the front vertical beam 81 on the side and the lower front end of the side plate 83 by the lower front beam screw 814.

The vertical surface of the rear board L-shaped mounting surface is located in front of the horizontal surface, and the lower end of the rear board assembly 3 is fitted against the rear board L-shaped mounting surface, thereby acting as a front limit and a lower limit for the lower end of the rear board assembly 3. Furthermore, after the lower end of the rear board assembly 3 is fitted against the rear board L-shaped mounting surface, it can be connected and fixed using the rear board assembly lower fixing screws 330.

[0124] It should also be noted that if Figure 6 As shown, the lower rear beam 7 is provided with a third threaded hole 77 at the lower mounting surface 71 of the back plate assembly, wherein the lower mounting screw 13 of the back plate assembly passes through the lower end of the back plate assembly 1 and is fastened to the third threaded hole 77 of the lower rear beam; the upper mounting surface 61 of the back plate assembly of the upper rear beam 6 is also provided with the same arrangement, which will not be repeated here; in addition, as Figure 7 As shown, the rear end portion of the lower rear beam 7 is also provided with a lower rear beam nut strip mounting groove 76 for mounting the lower rear beam nut strip 73, and is located on the front side of the lower mounting surface 72 of the rear plate assembly. Of course, the vertical surface of the lower mounting surface 72 of the rear plate assembly is provided with an avoidance groove connected to the lower rear beam nut strip 73 to ensure that the lower fixing screw 330 of the rear plate assembly can be fastened with the internal threaded hole of the lower rear beam nut strip 73 after passing through the lower end of the rear plate assembly 3; of course, the rear side portion of the upper rear beam 6 is also provided with the same arrangement, which will not be repeated here.

[0125] Furthermore, if Figure 1 As shown, the chassis frame provided by the embodiment of the present invention further includes a center beam 9;

[0126] The middle beam 9 is connected between the rear portions of the two side panel assemblies 8 and is located between the upper rear beam 6 and the lower rear beam 7 , and is used for assembly and connection with the middle portion of the back panel assembly 1 .

[0127] Among them, such as Figure 1 As shown, the two ends of the middle beam 9 are respectively installed on the rear of the two side panel components 8, and can be connected and fixed by the middle beam screws 817; the front side (front panel surface) of the middle part of the back panel component 1 can be installed and fixed on the rear of the middle beam 9, wherein, as shown in FIG.
